RIDING DISK PLOW.

SPECIFIGATION' forming part of Letters Patent No. 662,845, dated November 2'7, 1900. Application filed March 1'7, 1900. Serial No. 9,106- (No modelf To whom it may concern:

Be it known that we, EDMUND O. WESTER- VELT and CHARLES W. CLAPP, of South Bond, St. Joseph county, Indiana, have invented certain new and useful Improvements in Ri'ding Disk Flows; and we hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvementin riding disk plows, and has particular reference to (a) the mounting of the front staggered wheel and the means for adjustingthe same, (b) the means for attaching the draft or double tree to the frame, (0) the novel construction and arrangement of the scrapers for the disk plows, and (d) novel means for alining and locking the rear guide-wheels of the plows. These are the principal objects of the im provement; but other features and the advantages of the invention will be set forth in the detailed description following.

The invention therefore consists in the novel construction, combinations, and. subcornbinations of parts summarized in the claims appended to the following description of the plow illustrated in the accompanying drawings, in which Figure l is a perspective view of the complete plow. Fig. 2 is a plan View. Fig. 3 is a side elevation. Fig. 4 is a front elevation.

The plow consists, essentially of a frame A of approximately triangular shape in plan, to the base of which triangle forming the front of the machine are attached the draft devices. To the inclined furrow side of the frame are attached the cutting-disks, of which one or more may be used. In the drawings I have shown only one disk; but when more are employed they will simply be attached to the furrow side of the frame, one in advance of the other, as in the usual arrangement of gang-plows. To the land side of the frame is attached a land wheel B, mounted on a cranked axle B, which is adjusted by a hand lever B and segment 13 as usual. To'the front furrow side corner of the frame is attached a casting C, which may be flanged over the front bar of the frame and is seen red by bolts 0, which pass through slots 0 in the casting, so that the casting can be adjusted laterally upon the frame, if desired, to accommodate the wheel to the width of the furrow that isbeing cut. This casting is provided with forwardly-projeeting lugs 0 to which the clevis H or drafttrees may be attached. It is also provided with upper and lower pairs of eyes a and 0 in which are journaled short horizontal crank-shafts D D, the outer crank ends of which are journaled in hearings in a sleeve E, in which is journaled a shaft F, the lower end of which is inclined at an angle of about forty-five degrees and carries astaggered furrow or guide wheel 6. The upper end of the shaft F isbent inwardly over. the frame, as shown at F, and

to it is connected the tongue f, so that the wheel 6 is controlled by the movement of the tongue, and thus the plow is guided independently of the draft thereon. By reason of the double cranks D D the wheel 9 can be vertically raised and lowered without changing its inclination in the furrow by means of a crank d, attached to the upper shaft D and connected by a rod d to a lever (Z pivoted on the frame and provided with a hand-latch, as usual, adapted to engage a segment d on the frame, as shown.

Attached to the front bar of the frame beside casting C is another casting G, which is provided with forwardly-projecting lugs g similar to the lugs c on casting C, and, like the latter, adapted for the attachment of a clevis H. The draft-block G is also preferably flanged over the front bar of the frame and is secured thereto by means of bolts G, which may engage slots in the frame or in the casting G, so as to permit the lateral adjustment of the latter on the frame. The castings O and G thus permit of a range of adjustment of the point of attachment of the clevis to the frame as will best suit the varying conditions of the work to be done and the number of horses to be employed.

The rear end of the frame A is supported by a caster-wheel I, mounted on a crank-axle I, swiveled in the casting J, attached to the frame. Pivoted to the casting J beside the shaft I is a lever K, the lower end of which when the lever is in one position limits the motion of wheel I in one direction, but leaving it free to move away from it in the opposite direction; The wheel I follows in the furrow which has been formed by the disk immediately preceding it. When lever K is thrown backward, the wheel I becomes a free caster-wheel and can turn to the right or left. The lever K is thrown backward when the plow is turned to the right, and when it is again straightened in the furrow lever K is thrown forward and its lower end strikes against the horizontal portion of the crank axle I and forces wheel I back into proper position. This is practically quite important, for if the caster-wheel is left to swing freely it will not remain properly in place and will cause an irregular movement or cut of the plow. Further, by means of this lever the correct alinement of the wheel is obtained and insured While the plow is proceeding with its work, and the necessity of partially pulling the plow out of its course, as is necessary when a latch or lock is used, in order to get the wheel in alinement is avoided. A strap 70 maybe attached to castingJ below the pivot of lever K to relieve the latter of the lateral thrust on the end of said lever.

The lower front portion of casting .I is provided with a bearingj for the shaft 1 of the disk L, which is of ordinary construction.

The disk is provided wi th a scraper M, which,

because of its peculiar construction and adjustment, acts as a moldboard and will turn the furrow entirely over, as in an ordinary moldboard-plow. This scraper, as shown, is made to cover a little more than one-half of the disk and is located in rear of and extends slightly above the hub of the disk, being adjustably connected to'the rod m, which is in turn fastened to a bracket m on or secured to casting J. Just in rear of the disk L is attached a horizontally-disposed cutter 0, preferably a rotary one, mounted upon a shaft 0, which is journaled in a vertical sleeve P, attached to or formed on the casting J in rear of the disk. This cutter O operates at the bottom of the furrow to loosen the ground for the succeeding furrow, so that the latter can be easily turned over as a whole when the plow comes by the second time. The form of frame shown does away with the necessity for a plow-beam, and by reason of the ample adjustments provided for the clevis attachment the draft can be so equally balanced that the machine will be practically self-guiding. At least it can be very easily guided by means of the tongue, which has nothing to control except the furrow or guide wheel 6, and only a very small amount. of force is necessary to control its direction when at work.

Having thus described our invention, what we therefore claim as new, and desire to secure by Letters Patent thereon, is
